COUPLING MEMBER FOR SEPAB ABLE FASTENERS.

Application filed March '15, 1926,'Seria1 No. 94,711. Renewed June 23, 1928.

This. invention relates to coupling mem- 'b'e'rs employed in connection with separable fasteners employing two parts having interlocking members adapted to be coupled and uncoupled together by said member which is slidable longitudinally of the fasteners in this operation; and the object of the invention is to provideia coupling member of the class and for the purpose specified which is fashioned from a single body of predetermined material', preferably metal, by means of dies or molds; a further object being to provide a unitarily formedmember of the class specified in which the diverging channels are accurately formed, said channels having apertures opening outwardly through the sides of the coupling member to permit of the free passage of thet shanks of the fastener therethrough; a furtherobj'ect being tofprovidea coupling member of the class described with a finger piece guide and support formed integral with saidmember in the operation of 1 l casting the same and providing movement of the finger piece longitudinally of the coupling F member in the operation thereof, means being provided to permit of the mounting of a finger piece whichis i dependently formed, in connection with said coupling member, and

' for retaining the same against displacement .3 therefrom; Ia still further object being to provide a coupling member, the diverging channels of which are subdivided .by an intermediate body portion which serves to join the upper and lower portions of said member or the opposite side faces thereof, and said body portion having forwardly directed finlike extensions extending into that part' of said member where the'diverging channels 1ntersect; I and with these and other objects in view, the invention consists in a coupling member of the class and for the purpose speci- 'fied which is simple in construction and operation, eflicient in use, and which is constructed as. hereinafter described and claimed. 5 The invention is fullydisclosed in the following specification, of which the accompanying drawing. forms a part, in which the separate partsofmy improvement are designated by suitable reference characters'in each of theviews, and in which':

' In Fig. 1 of the drawing, I have shown for the purpose of illustra-ting one use of my invention, the two parts 5 and f a separable fastener, each part having link members 5* v and 6 respectively, the link members 5" being adapted to interlock with the link members 6 to secure the separate parts 7. and 8 of a garment or the like together. At 9, in Fig. 1 :of the drawing, I have shown one of my improved coupling members mountedupon the parts 5 and 6 of the fastener or the link members 5 and 6 thereof.

In the production of couplingmembers of the class under consideration, it is customary to construct these devices of two or more parts coupled together, by riveting, welding or otherwise to form a coupling member having diverging'channels and other structural features, but this. method of procedure is rendered inexpensive and difficult in the handling necessary to performthe several operations, the cost of such devices, and the loss sustained in imperfect devices caused by inaccurate assemblage and the like; and it is the purpose of my invention to overcome these objectionable features and to reduce thmanufacturing cost .to the greatest possible extent in the production of perfect coupling mem In carrying my invention into effect, 'I produce a unitary body byv means of die casting .or moldin a suitable metal or any other 1 hard and dura le substance that will be suitable for the desired use. In the construction shown, the coupling member comprises two substantially similar side portions 10 and 1 1 joined at one end by a partition, wall member or body 12 forming diverging -'channels 13 anti 14 spaced apart by the member 12 at one end of the device. Said channels intersect at the contracted end of the device as clearly seen in Fi 3 and 4 of the drawing. The end of the wall member 12 adjacent the contracted l I I end of the channels 13 and 14 is beveled as seen at 12', Fig. 3 of the drawing, and extends in finlike members 12 onto the inner faces of D0 finger piece 19 is adapted .to be placed'to perthe side portions 10 and 11 of the device as seen in Fig. 2 of the drawing.

The channels 18 and 14 are substantially circular in form in cross section and open outwardly through the opposite sides of the coupling member through a ertures 15 and 16 through which apertures, t 1e shankportions of the devices 5 and 6 or the links 5 6 thereof are adapted to pass.

The construction of the coupling member 5 or the formation or arrangement of the channels 13 and 14 therein which intersect at the contracted end of the device and diverge into separate discharges at the fiaredend of the device, is such as to permit of the free movement of the coupling member 9 over the links of the fasteners 5 and 6 in the operation of coupling and uncoupling the same, it being understood that the fin-like extensions 12 serve to enter the crevices formed between the links 5 and 6 of the fastener when coupled together, thus facilitating the free and easy operation of the coupling member in coupling.

form a contracted end 17*, note Fig. 2 of. the a drawing. Extending centrally'and longitudinally of the outer face of the coupling member 9 at one side portion thereof, the side portion 10 in the construction shown, is a rib 18' T-shaped in form in cross section and forming a slideway for a finger piece 19, said ribtforming at its opposite sides, channels 20 into which the yoke-shaped end 21 of the mit of the movement of the finger piece longitudinally of the coupling member from one end portion thereof to the other. The chan nels 20 are closed at the contracted end of the of the hand to facilitate the operation of the coupling member 9. However, it will be understood that I am not necessarily limited to any specific form of finger piece nor am I necessarily limited to the specific arrangement of the structural features of the device herein shown and described nor the use herein illustrated, and various changesin and modifications of the construction herein set out may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is I 1. A coupling member for separable fasteners comprising a unitary body consisting of substantially similar side portions united by a partition. wall adjacent one end of the couside portions, said channels intersecting at one end of the coupling member and diverging atthe other end thereof, said partition wall being tapered in the direction of the intersections of said channels, said channels opening through apertures at the opposite sides coupling member 9 as seen at 22, Fig. 2 of drawing. It will be noted that the channels 20 normally open out through the rib 18 at the end portion 23 thereof as seen at 24 to .permit the mounting of the finger piece 19 in Q connection with the rib '18. But, when said finger piece is mountedin position by passing the forked end 21 thereof over the projecting lip 25 of the rib 18, said rib is forced inwardly into the position shown in full lines in Fig. 2 of the drawing to prevent the accidental displacement of the finger piece 19.

It will be apparent that the. rib construction,18 with the channels 20 at the opposite sides thereof, will permit the finger piece 19 to be mov edfrom one end portion of the coupling member 9 to the other end .portion thereof. As seen in Fig. 2 of the drawing,

' the finger piece 19 is brought into axial alineof the coupling member and formed between the side portions thereof, said channels being substantially circular in form in cross section, a rib integral with one side face of said coupling member and extending centrally and pling member, channels formed between said longitudinally thereof; and said rib having channels in the opposite faces thereof.
